AMALGAMATOR.

SPECIFICATION forming part of Letters Patent No. 366,130, dated July 5, 1887.

Application filed May 4, 1886. Serial No. 201,078. (No model.)

To all whom it may concern.-

Be it known that 1, ANDREW N. Romans,- of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Amalgamators, of which the following is a full, clear, and exact description.

The invention consists, in substance, in the construction of the cylinder or casing of the apparatus, and which is to receive the ore to be treated,with a chute at the top for entering the ore into it, and with an opening between the top and bottom for the discharge of the gangue; and also in a groove or channel leading along the bottom of the cylinder or casing, and from end to end thereof, for the circulation of mercury and preserving its level, said groove being open at both, ends to the chamber of the cylinder, but otherwise closed by the copper lining, and all otherwise substantially as hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, the apparatus of this invention is illustrated. Figure 1 is a longi tudinal section of the cylinder or casing with the screw-conveyer in elevation and both cylinder and screw broken away. Fig. 2 is a vertical cross section on line 2 2, Fig. 1. Fig. 3 is an end view of the cylinder or casing with its upper section thrown back.

In the drawings, A is a horizontal cylinder or casing having bearings at each end for the shaft containing the screw and agitating-blades B, and which shaft, as also its blades, rotates within said casing, and all so as to convey and agitate the ore placed therein from the end 0 to the end D of the cylinder.

E is an opening in upper part of cylinder for feeding the same with the ore to be amalgamated and separated, and F is a tap-hole in bottom of cylinder, suitably closed by a plug or cap. The feed-opening E is at the end 0 of the casing, and the casing at its other and opposite end,D,is provided with an outlet or discharge, G, for the gangue, which outlet is be tween the top and bottom of the casing, thus enabling the gangue to be discharged without requiring it to be lifted therefor. The casing A is in upper and lower sections, Figs. 2 and 3, and the upper is hinged at one side to the lower, and each is made with flanges H to set upon each other, and the two sections on their side 'J, opposite to their hinge K, are adapted to be bolted through the flanges H, and thus the sections of the casing are closed and the casing made tight.

L is a groove or gutter extending along the length of the casing and at its inner and un-' der side, and M is a lining of copper about the inside of the casing and covering said gutter L.

N is a hole through the copper lining M at each end of the gutter L, and thus communication is rnade between the casing and the gutter, and, in addition to these holes, small perforations N N may be also made through the lining and opening to the gutter. The gutter L secures circulation of the mercury from end to end of the casing, and keeps the mercury always level in the cylinder A. The copper lining ofthe cylinder is made an amalgamating-surface by the application of men cury thereto. The location of the discharge G for the gangue between the top and the bottom of the casing,while securing, an escape or discharge for the gangue, prevents a filling of the casing, and thereby affords the ore in the casing an opportunity to be the better agitated from the action of the screw-con Veyer and exposed to the amalgamating action of the apparatus.

Having thus described my invention, I claim- In an amalgamating ore'separator, in 00111- bination, a horizontal cylindrical casing, A, in upper and lower longitudinal sections hinged together and closed at both ends, a chute, E, in the upper side and at or near one end of said casing, through which to enter the ore *into the casing, a discharge, G, between the upper and lower sides of .said

casing, and at or near the end thereof opposite to said chute E, through which to discharge the gangue, screw and agitatingblades B, carried by a common shaft longitudinally placed in and adapted to turn in bearings of each end of said casing, a longi- In testimony whereoflhave hereunto set my tudinal gubter,L,a1ong the bottom of said cashand in the presence of two subscribing witsing, and a lining, M, of copper, lining the inncsses.

terior of said casing; covering said gutter, and ANDREV N. ROLLINS. 5 having holes N through it at each end, sub- 'itnesses:

stant'ially as described, for the purposes and ALBERT WV. BROWN,

operations specified. H. 11 MOKEEVER.
